Thermostatic angled valve set kfa² 1/2" model 757-100-07-BL

Thermostatic angled valve set kfa² 1/2" model 757-100-07-BL is a compact valve assembly designed for angled (corner) installation on radiator inlet connections with 1/2" threads. The set enables thermostatic control of radiator temperature and manual flow adjustment, combining a temperature sensing head interface and a lockshield-style return valve in an angled configuration. The matte black finish is intended to integrate with modern interiors while providing a durable surface for wall-mounted radiator fittings.

Advantages

The angled design reduces protrusion from the wall and simplifies installation where straight valves would not fit. Built for compatibility with standard 1/2" radiator connections, the set enables precise room temperature regulation through a thermostatic head (sold separately) while allowing independent flow balancing. The matte black finish offers consistent aesthetic integration and corrosion-resistant properties suitable for typical domestic and commercial heating environments.

Suitable for

• Wall-mounted radiators with angled inlet requirements
• Domestic central heating systems requiring thermostatic radiator control
• Commercial heating installations where compact valve fittings are needed
• Renovation projects aiming for a discreet, modern finish

Key specifications

• Connection size: 1/2" inlet threads compatible with standard radiator fittings
• Configuration: angled (corner) valve set for inlet and return
• Functionality: thermostatic valve interface for temperature control and manual flow balancing
• Finish: matte black surface treatment
• Mounting: wall-mounted radiator installation

How to use

Install the angled valve set on the radiator inlet and return according to standard plumbing practice for 1/2" connections, ensuring seals and thread tape are applied where required. Attach a compatible thermostatic head to the thermostatic valve interface to enable automatic temperature regulation; the lockshield/return valve should be adjusted manually to balance system flow. Commission the system by flushing and filling the circuit, then set the thermostatic head to the desired room temperature and fine-tune the return valve for correct radiator heat output.

Usage recommendations

For reliable operation, pair the valve set with a thermostatic head from the same compatibility class and perform periodic checks for leaks and corrosion. During installation, follow local plumbing codes and use appropriate fittings; consider professional installation if you are not experienced with central heating systems.
